Semiconducting heterostructures with type-II band structure have attracted much attention due to their novel physical properties and wide applications in optoelectronics. Herein, we report, for the first time, a controlled synthesis of type-II ZnS/SnO2 heterostructured ribbon composed of SnO2 nanoparticles that uniformly cover the surface of ZnS ribbon via a simple and versatile thermal evapora...

We report an rGO/Fe2O3/SnO2 ternary nanocomposite synthesized via homogeneous precipitation of Fe2O3 nanoparticles onto graphene oxide (GO) followed by reduction of GO with SnCl2. The reduction mechanism of GO with SnCl2 and the effects of reduction temperature and time were examined. Accompanying the reduction of GO, particles of SnO2 were deposited on the GO surface. In the graphene nanocompo...

A facile and potentially scalable synthesis route to obtain SnO2-carbon composites was developed. SnO2 nanoparticles were deposited on the surface of two types of graphitic carbon: a) commercial porous graphite (HG) and b) graphitic carbon nanostructures (GCN). The synthesis procedure consists of two simple steps: i) room temperature formation/deposition of SnO2 nanocrystals and ii) thermal tre...

In this paper, hierarchical Ag-decorated SnO2 microspheres were synthesized by a facile one-pot hydrothermal method. The resulting composites were characterized by XRD, SEM, TEM, XPS, BET, and FTIR analysis. The catalytic performances of the samples were evaluated with the reduction of 4-nitrophenol to 4-aminophenol by potassium borohydride (KBH4) as a model reaction. Time-dependent experiments...

Chestnut-like SnO2 and SnO2/C nanocomposites with hierarchical structures are synthesized by hydrothermally oxidizing Sn nanoparticles in glucose solution. Structural characterizations using SEM and TEM reveal that the SnO2 nanoparticles are composed of numerous, randomly arranged SnO2 nanosheets with hollow cores. Owing to the short electron and ion diffusion distances and transformation strai...

In this paper, we report the first time preparation of SnO2 nanoparticles (NPs) using a green chemistry method. The leaf extract of Plectranthus amboinicus was used as reducing and stabilization agent for synthesizing SnO2 NPs. The synthesized SnO2 NPs were characterized by SEM, EDX, XRD and UV-vis spectroscopy. Results showed that the biosynthesized SnO2 NPs owing a high purity. The photocatal...

In this report, we show for the first time that SnO2 nanowire based dye sensitized solar cells exhibit an open circuit voltage of 560mV, which is 200mV higher than that using SnO2 nanoparticle based cells. This is attributed to the more negative flat band potential of nanowires compared to the nanoparticles as determined by open circuit photo voltage measurements made at high light intensities....

Nanoparticles are widely used in different applications such as cancer cell treatment and antibacterial agents. SnO2 nanoparticles were synthesized successfully by hydrothermal method and subsequent calcination using Tin (II) chloride- dihydrate, Sodium hydroxide, in presence of Hexadecyltrimethylammoniumn bromide (CTAB) as Surfactant. These nanoparticles were characterized by using Fourier tra...

SnO2:5Tb (SnO2 doped with 5 at% Tb(3+)) nanoparticles were synthesised by a polyol method and their luminescence properties at different annealing temperatures were studied. Characterization of nanomaterials was done by X-ray diffraction (XRD), Fourier transformation infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM). XRD studies indicat...
